2011 Leaf Springs Compared to 08-10?

Anyone know the difference between the 2011 Leaf Springs compared to the 2008-2010 Leaf Springs? My 2008 Leaf Spring has five leafs plus the overload, and I have heard talk of the 2001 Leaf Springs only having three leafs.

Just curious what the differences are, ride wise, load capacity wise etc.

My F350 has 3 thick leaves plus an overload. Rides twice as good as my 08 did.

My 2011 F250 seems to handle the 5th wheel hitch weight about the same as my 2001 did with only 2 main springs plus the overload on the bottom. It sits level with about 1500 pound hitch weight and a little higher in the back with no weight involved. The ride on the 11 is much better.

I find the 2011's sage less or as much as the 08's . Being that I've had both, nut the ride quality and control and sound is way better in the new ones

Thanks for the link!!! Here is what it sais:

The suspension has been tuned up, too. The shocks have new internal valve settings and the spring rates have been adjusted for better ride comfort. In 2008, Ford introduced its 3-plus-1 spring pack for both the diesel and gas trucks but the 2011 model SD pickups with diesel engines are setup with a new 2-plus-1 kit. Brewer said the 2-plus-1 setup reduces some of the spring binding from friction that drivers felt as a secondary impact after hitting road bumps. It also saves weight for improved fuel economy.
